I can send the patch to gcc first.  I see that gcc's dwarf2.{h,def} has
some new things that need to be sync'ed anyway.

For binutils-gdb, I just thought that there might be other users of dwarf2.def in
the tree that would break if I don't update them to add the new macros.
I see that elfcpp/dwarf.h includes dwarf2.def, it probably needs to be
updated.  However, I didn't see anything break when doing a default
build of binutils-gdb, so I need to figure out who uses this.  At first
glance it seems to be gold.
